INK FG'UNTAIN FOB, PRINTING Application filed June 16,

The present improvements have regard more particularly to the provision of a fountain for supplying ink to a printing); press of the so-called platen or Gordon type. One important object of the invention is to so construct such a fountain as to permit its ready disasseinbly for the purpose of cleaning. At the same time various novel adjustments are incormirated both for the support of the fountain and in its con struction proper, whereby proper contact with the ink distributing rolls may be secured as well as necessary variation in the rate at which ink is fed to the latter.

To the accomplishment of the fore oing and related ends, the invention, then, consist of the means hereinafter fully described and particularly pointed out in the claims, the annexed drawings and the following description setting: forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings Fig. 1 is a broken side elevation of a Gordon or platen press equipped with an ink fountain embodying our present improvements; Fig. 2 is a similar side elevation, on a somewhat larger scale, of such fountain by itself with certain parts thereof differently disposed; Fig. 3 is a longitudinal section on a vertical median plane of the fountain; and Figs. 1, 5 and 6 are transverse vertical sections thereof taken on the planes r spectively indicated by the lines 4-4, 5-5 and 66, Fig. 3.

Of the press, which is of familiar construction, only those parts immediately associated with the fountain shown in Fig. 1, viz, the form carrying; bed 1 (upper portion only), the disk 2 and the oscillatory roller frame 3. The ink fountain of pres cut interest is supported at the rear of aid disk 2 upon an arm 4 that is suitably secured to the disk bracket 5. The outer por tion of said arm 4 is disposed so as to lie substantially in the same plane, or in a plane parallel with disk 2, and is provided with a longitudinally extending: slot 6 (see Fig. 3), which serves in conjunction with a set bolt 7 adjustably to secure to said arm a 1923. Serial No. 645.836.

block 8 that forms the base to which the body 9 of the fountain is pivotally secured about an axis lying; transversely of such slot. The body 9 is sustained in desired angular position about such base 8 by means of an adjusting screw 10 threaded in a suitable opening in arm 4: a short distance below the lower end of slot 6 therein, as will be readily understood from an inspection of Figs. 1, 2 and 3. I

Such body 9 is in reality merely an open frame, the respective side portions of which are formed near their outer ends with suitable open bearings 12 for the reception of the spindle 13 of the fountain roller 14. The latter is provided on its one end with a ratchet wheel 15 that is fixed to its spindle and with an oscillatory lever 16 that carries a pawl 17 adapted to engage with said ratchet wheel. A rod 18 serves as a link operativcly to connect the outer end of said lever 16 with roller frame 3 so that upon oscillation of the latter, said pawl will be actuated to rotate ratch t wheel 15 and thus the roller 14 in a counter-clockwise direction, as viewed in Figs. 1, 2 and 3.

Pivotally attached to frame 9 near its rear end is a supplemental frame 20, the side portions of which are respectively formed near their outer ends with projections 21 that are adapted to hold the spindle 18 in bearings 12, in fact to form complementary portions of such bearings. In order to hold Sr id supplemental frame in position thus to lock the spindle in place, two resilient latches 22 are secured to the front ends of said side portions, respectively, the side portions of the main member 9 beingr formed with shoulders 23 wherewith such latches are adapted to engae'e. A. bar 241 connects the two and forms a convenient handle whcr v they may be simult ieously withdrawn from such engae'ement with shoulders and the supplemental. member raised into the position shown in Fie 2. In such raised position of supplemental frame the ro ler 1 may be directly lifted out of its bearings 12 and so may the cup 25 be similarly lifted from its resting place in the lower frame 9. This cup consists simply of a sheet metal plate with triangular sides that is norn'iallv supported on the member 9 in the "oration shown.in Fig. 3 where the roller 14 closes more or less completely the forward open end of the space defined by such side walls. Indeed said roller completely closes such space transversely by fitting snugly between the side walls, the opening between the bottom of the cup and the roller being rendered adjustable, as will now be described.

The rear end of the cup is provided with a downwardly projecting lug 26 that is formed on each side with an approximately semi-spherical recess 27 into which spring pressed balls or plungers 28, suitably held in cages 29 mounted in the adjacent side portions of frame member 9, are adapted to enter. hen said balls or plungers thus engage the recesses 27, the cup is in effect pivotally attached to said frame member at its rear end and its forward end may then be raised or lowered by means of a transverse cone-pointed adjusting screw 30 that is mounted in one side portion of said frame member so as to engage a transversely inclined cam face 81 on the adjacent under portion of the cu (see Fig. 5).

A plate 32 pivotally attached at its rear end to the supplemental frame member and provided at its forward end with a suitable knob 33 serves as a cover for the fountain when in its lowermost position, as shown in Figs. 1 and 3; However, upon raising such cover, access to the interior of the fountain for the purpose of replenishing or distributing the ink supply in the cup is immediately had. Should it be desired to remove such cup or the roller for any purpose, such as in order to clean the same, it is merely necessary to pull outwardly on handle bar 24, whereupon the supplemental frame 20 may be raised. the roller lifted out of its bearings and the cup detached from the spring pressed plungers 28. To replace the parts in question is, of course, an equally simple operation. It will also be noted that by means of the adjustable se screw 7, the fountain as a whole may be moved towards or from the axis of the disk 2; that by means of screw 10, the fountain as a whole may be rocked about base 8 to raise or lower the roller 14 with respect to said disk; and that by means of conepointed screw 30. the cup within the fountain may be independently adjusted with re spect to said roller so as to feed a film of ink of any desired thickness. Finally, the base 8. and so the fountain as a whole, may be oscillated about set-screw 7 as an axis so as to vary the angular position of the roller 14L with respect to the disk 2. The extent to which such roller contacts with the ink-distributing roller of the press may be thus correspondingly varied and the rate at which ink is fed to such last-mentioned roller further controlled in this way.

Other modes of applying the principle of our invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

We therefore particularly point out and distinctly claim as our invention 1. In a device of the character described, the combination of a main frame member having side portions formed with aligned open bearings, a roller removably journaled in said bearings, a supplemental frame, conr plemcntary bearing members on said supplemental frame, resiliently supported latches for securing said supplemental frame to the main frame, a cup open above and at its forward end, adjacent said roller, and means for adjusting the position of said cup.

2. In a device of the character described, the combination of a main frame member having side portions formed with aligned open bearings, a roller removably journaled in said bearings, a cup open above and at its forward end, said cup lying to the rear of said roller and the latter forming a closure for such forward cup end, opposed resilient members engaging the end of said cup whereby the latter is pivotally secured to srid frame. and means adapted to adjust the position of said cup about its pivotal axis.

3. In a device of the character described, the combination of a main frame member having side portions formed with aligned open bearings, a roller removably journaled in said bearings, a cup open above and at its forward end. said cup being removably pivotally mounted in said frame to the rear of said roller and the latter forming a closure for such forward cup end, and means adapted to adjust the position of said cup about its pivotal axis, said means including a member mounted in said frame so to be transversely adjustable thereof and having a cam engagement with said cup.

4:. In a device of the character described, the combination of a main frame member having side portions formed with aligned open bearings, a roller removably ournaled in said bearings, a cup open above and at its forward end, said cup lying to the rear of said roller and the latter forming a closure for such forward cup end. opposed resilient members engaging the end of said cup whereby the latter is pivotally secured to said frame, and means adapted to adjust the position of said cup about its pivotal axis, said means including a transversely adjustable screw mounted in said frame, and a transversely inclined cam face on the ad jacent under portion of the cup.

5. In a device of the character described, the combination of a main frame member havin side portions formed with aligned open bearings, a roller removably journaled in said bearings, a cup open above and at its forward end removably fitted to said frame immediately back of said roller, the latter forming a closure for such forward cup end, a supplemental frame hingedly attached at its rear end to said main frame and adapted in one position to lock said roller in such bearings, and a cover adapted to fit over said supplemental frame, said cover being 10 hingedly attached about the same axis as said supplemental frame.
